SHOCKING video has emerged of a 13-year-old girl being punched, kicked and kneed in the head by a group of six teenage girls at a railway station in Western Sydney.

SHOCKING video has emerged of a vicious assault on a teenage girl and a friend at a Sydney railway station.

The 13-year-old was punched, kicked and kneed in the head by a group of six teenage girls at Blacktown railway station last Tuesday afternoon as she and a 15-year-old friend and two other friends waited for a bus.

A shocking video, allegedly captured by one of the assailants’ friends, shows the gang cursing and threatening the 13-year-old before one attacker throws a coward punch and the group launches in on the defenceless teenager.

Her 15-year-old friend forced herself on top of the cowering victim, protecting her head until passers-by eventually pulled the pack of girls off.

The two teens said the assault was unprovoked.

“I was scared, I didn’t know when it was going to stop,” the younger victim said.

“I’m just so thankful for what (my friend) did, it just showed me that she’s a friend to me. If I was by myself well I don’t want to think about what might have happened.”

A police spokesman said a 16-year-old Mt Druitt girl arrested at the scene would be dealt with under the Young Offenders Act and investigations were still pending.

A Sydney Trains spokesman said the “safety and security of our customers and staff is the top priority”.
